PT, I think it's generally true that dietary cholesterol from sources like egg yolk (not oxidized, not rancid, not overheated, not processed) will not, as a standalone, affect blood levels in a way that should cause concern. This is a VERY general statement - because other risk factors, dietary and bodily weaknesses, and genetic heritage can play a role in how the body reacts to a myriad of circumstances that could affect cholesterol levels. There ARE "hyper-responders" to dietary cholesterol. For this reason, cholesterol levels (to me) are not irrelevant, but mis-interpreted and ill-used in the medical profession. And it breaks my heart when someone throws away that nutritious, delicious yolk! Especially since egg whites are far more likely to irritate the gut.

Caveat: supermarket eggs are high in PUFA. More below. Find pastured eggs and ditch the omega-3 eggs.

IF an individual has high serum cholesterol, it's much more valid to assume that the body has called on cholesterol to heal and protect itself from rancid fats and the affects of a diet high in processed foods. (Are you having a cinnamon roll with those eggs? Wink, wink)

Weston A. Price is my favorite source for "myths and truths about cholesterol."

I think what people often blame on egg yolks, etc. is usually a result of OTHER dietary factors present. Cholesterol is a healing substance, and when blood vessels experience weakness or damage, cholesterol rushes in to repair. There are so many interactive factors here, however, that I think it would be best for you to peruse these resources so you can formulate an answer that's most appropriate for your dad.

i've come to understand the same thing as cavegirl said...cholesterol is good for you. great for you, even. the real foods that are raising blood cholesterol are the foods that increase blood sugar: sugar, grains, processed foods, etc.

i've also learned that there is a lot of confusion on what a good cholesterol number really is. my parents and wife have been nagging me like crazy to get my cholesterol checked, and while they keep talking to me about what it should be--and might balk at what it is--they don't really understand it. i've asked each of them to explain cholesterol to me...and they just end up screaming at me about challenging everything.

The answer is that it depends. There are cholesterol hyperresponders who do increase cholesterol (about 2.5 mg/dl per 100mg of cholesterol) or hyporesponder whose total LDL doesn't change. Most people are hyporesponders.

But the thing is that in hyper-responders, the change in LDL is a positive one, yielding a less atherogenic profile than the group with the placebo. http://www.ncbi.nlm.nih.gov/pubmed/15164336?ordinalpos=&itool=EntrezSystem2.PEntrez.P ubmed.Pubmed_ResultsPanel.SmartSearch&log$=citatio nsensor

Don't have reference, but I recall reading that dietary cholesterolis at most 15% of blood cholesterol. Our bodies are very good at synthesising it because we need it, especially our brains. Is it any wonder that statins have such bad side-effects, including reduced mental faculties

BTW all trials of drugs designed to block the absorption of dietary cholesterol have shown that those drugs increase other causes of mortality. And there is no evidence that margarines etc enhanced with phytosterols to reduce cholesterol absorbtion have a net health benefit
